I have a 1999 Honda Accord EX V6 That I have been battling with now for what seems like forever. I have installed a 562t and a 555h passkey. I know that all connections are made properly. Here is the issue that I am having, The remote start will only work sometimes. It engages every time and no matter where the cranking time is set it doesn't matter. Whats funny is if I put a battery charger on the car and remote start it, it will start every time. I can always start the car with the key reguardless of charger or not. Please Help me resolve this. Daniel

i would try getting the power for 562t from an other source like run a dedicated line from the battery. and you should use the tach diagnostic plug for a true tach wire it is a blue single wire plug usually found on either strut tower inside engine bay. and make sure your grounds are solid.

mecp certification is not always needed. I have it and it has not helped me out at all. my experience out shines it.

I have got all of the power points including the passkey on the positive battery terminal. The tach wire on this vehicle is different than what i have seen. When turning the ignition on the wire shows 12v there is no variation with RPM. So it didnt make a difference whether I did voltage or tach sense. Daniel

ok well when you can measure the batteries voltage when you are resting. key off dorrs closed etc. battery might not be strong enough. and the key even tho you may not think it but you hold the crank longer than most times that rs systems can be programmed. so those extra second on the low battery might be just enough., just a thot.

If your tach connection doesnt fluctuate with rpm then it is not the right wire, keep testing and look for variation.

if the car always start with the key and only sometimes with the r/s then that means that the cars battery is getting weak. my car has done this to me and as soon as i replaced the battery it started everytime with the r/s.

Are you setting your meter to AC Volts, to measure the tach? It's not DC. Just a thought! ------------- Good Enough Isn't!

Ok I havent done one of these in a while your right the tach wire is AC instead of DC probably had the right wire the whole time.  Also I forgot to mention one additional thing in the beginning of the post. It will also start everytime if I have the key in the ignition(reguardless of additional power). but also everytime without the key as long as I have an additional power source connected (battery charger). Just doesnt make a lot of since. This is the first honda I have done an maybe the last. LOL Amercian Vehicles are easy ive done dozens of them. This is my girlfriends car so I can keep trying stuff with no time limit. Thanks, Daniel

your 555h might be funky/. the car is generally very easy

also just a quick thing the car was actually manufactured in 10/98 Would that make a difference?

hey did you ever get it working?? i have the same exact car and going to install a viper 5900 very soon. i also have the 555h.
let me know ok?

Yes replacing the battery did a wonder for mine, but I kind of knew that when it was doing what it was doing like it would only work when I had a battery charger hooked up to it. Thanks, Daniel

thats good to hear that the 555h worked since your car is a late 98 manufacture date. mine is actually a 11/98. would you mind helping me with the 555h install and where you found the tach wire?

I have no problem with that the tach wire is located about 1ft behind the battery towards the firewall. It is hanging on the finder, It is a two pin connector with only one 18ga blue wire running to it. It will have a black rubber boot on it. As far as the 555h do you have the instructions that came with it? Make sure that you do set your meter to ac voltage when you are testing the tach wire. If you have it set on DC it will just show 12v when the ignition is on. Whenever you power your 555h use the white wire in the ignition harness.

I did a lot of looking around. I think I can do the 555h with no problems. As for the tach wire, is this it:
It does not connect to anything right? So i would just connect the tach wire from the alarm to this point (circled in red)?
Thanks again for the info. sorry to hj your thread

That is indeed the tach test connector there.

alright cool. I tested the voltage out with the dmm set to AC and it came back with 1.46v
so the whole point of this wire is just to test out the voltage? other than that it has no use?
also would i just connect this to the alarm?

The purpose of the wire on the car is so that a Honda dealer mechanic can have a quick and easy way of displaying engine RPM while servicing the vehicle. It may also control the tachometer in the gauge cluster.
The purpose of the connection to the remote start is so that it knows the engine has started and it can stop cranking. When the RS recognizes the tach pattern programmed to it, it will immediately release the starter relay output. As discussed in many other posts this is superior to voltage sensing in which the RS will tend to crank the starter just slightly too long or too short.

What specifically are you thinking you'd need relays for?

You do not need any relays for a basic alarm, trunk pop, and remote start install. The only thing that you would need a relay for is like doing your windows, sunroof, or anything like that. Since the trunk pop is a negative wire you just hook the aux from the brain into the wire.
